BIO 201 EXAM 1 WITH CORRECT
ANSWERS 2025
Homeostasis correct answers >> Maintenance of a relatively
stable internal envrionment despite continuous changes.
Negative feedback loop correct answers >> Maintains a state
of dynamic constancy within internal environment; stimulus and
response work in opposition directions.
Requires:
-a sensor/receptor to detect change
-an integrating center/control center to coordinate response
-an effector to execute the response
5 main steps to maintain homeostasis when there is an alteration
in balance correct answers >> 1:stimulus:produces a change
in variable
2-sensor/receptor:detects change
3-input: information sent along afferent pathway to control center
4-output: information sent along efferent pathway to effector.
5-response:response of effector feeds back to reduce the effect of
stimulus and returns variable to homeostatic level.
